The procedure of treating the saphenous vein is generically called EVLA (Endovenous Laser Ablation). Some companies have copyright names for this, "EVLT" (Diomed), "Closure" (VNUS Technologies), "ELVes" (Biolitec). There are other laser companies such as Cool Touch that do not copyright their procedures. Several studies have shown, and it is safe to say that all of these procedures work very well (>95% effective) at treating the saphenous vein.
Several years ago, Advanced Vein Center received a copyright for LES-Vein as the name of our ablation procedure.
